What is the best gram BB to use in a KWA MP7. .20g or .25g? I know .30g is to heavy because the gun isnt even 400 fps. Also I am aware I have this posted on the G36c, M4/M16 forums too but both are different I just want the optimal bb gram for my guns. Thanks

It is usually the best all around but then i got to thinking i am not even really using the hop up now with .25 so i thought if i got .30g i would have a better more accurate bb due to weight and just turn the hop up..up..and then get same distance with more accuracy.
